For applications where precise multi-positioning is required, our linear bellows drives provide exceptional resolution (two- times better than conventional units), a guaranteed minimum lifetime of 10,000 cycles and the ability to easily motorise in the field.

The linear bellows drives (LBDs) are a range of cost-effective UHV bellows-sealed devices that provide smooth and precise linear motion solutions for low-load applications with 0.01mm linear resolution. They are available on a 34mm (1.33″) OD CF flange as standard or 70mm (2.75″) OD CF flange option with a range of strokes up to 150mm. They are ideal for simple linear motion applications through to precise positioning, such as required for beamline diagnostics.

The LBD is manufactured and assembled to high tolerances using quality materials throughout, including 316L bellows, which offer a guaranteed minimum lifetime of 10,000 cycles.

A simple user-friendly retrospective motor upgrade is available, which includes home and limit switches for positional accuracy that can easily be removed for bake-out. The LBD range offers four interchangeable actuation methods; simple push-pull rod, micrometer-style actuation, high-precision motorisation and pneumatic.
